IMPROVEMENT IN METALLIC PAPER-FASTENERS.

Specification forming part of Letters Patent No. 208,836, dated October8, 1879; application filed Sept-ember 20, 1877.

To all whom it may concern:

Be it known that 1,-GEORGE XV. MoGILL, of the city and county of NewYork, in the State of New York, have invented a new and usefulImprovement in Metallic Fasteners; and I do hereby declare the followingto be a full and exact description thereof, reference being had to theaccompanying drawing, makin g part of this specification, and to thefigures and letters of reference marked thereon, in which similarletters of reference indicate corresponding parts.

My invention relates to that class of metallic fasteners known to thetrade as McGills Paper-Fasteners, wherein the fastener being in a Tshape its shanks make only a single hole in the papers or other articlesit is designed to connect, the two shanks opening from each other afterpassing through the papers and confining said papers between said shanksand the head of the fastener.

My invention which I now seek to patent consists of a T-shaped fastener,having its shank split vertically from its point to its folded head, toform two prongs arranged edgewise, to operate in the mannerhereinafterdescribed.

In the drawing, Figure 1 represents the blank from which the fastener isformed. The upper portion of this blank is folded at the points marked aa a, so as to form the fastenerhead A, as shown in Fig. 2. B B are theprongs of the fastener, which are formed by the vertical split 0.

Fig. 2 represents the fastener completed, with its head folded intoshape. A is its head and B B its shanks.

Fig. 3 represents a fastener so made, capped with a metallicbutton-head, D.

Fig. 4 represents a blank, showing the fastener and button-head made inone piece; and Figs. 5 and 6 represent the same bent into form andcapped.

In binding papers and other suitable articles with this fastener, itssplit shank is run through the said articles until its head rests on thesurface of one side thereof, when its shanks are bent apart and forceddown on the opposite side of the article, so as to clamp the samebetween them and the fastener-head.

'What I claim herein as my invention, and desire to secure by LettersPatent, is-

1. As an improved article of manufacture, a metallic fastener consistingof the pointed prong split vertically through its center to the head A,so as to form the two prongs B B, ar ranged edgewise to each other, thehead A bein g folded, as herein shown, and at right angles to the prongsB B, the whole being constructed of a single piece of material, andadapted for use substantially as shown and described.

2. A paper-fastener consisting of a head formed from portions a a a anda pointed shank portion split vertically through its center, formingfastening-prongs B B, all from a single piece of metal, substantially asshown and described.
